S. Patir et al., INTERMEDIATES FOR THE SYNTHESIS OF TETRACYCLIC INDOLE ALKALOIDS - SYNTHESIS OF 4-AMINOTETRAHYDROCARBAZOLE DERIVATIVES, Journal of heterocyclic chemistry, 34(4), 1997, pp. 1239-1242
An efficient method for the synthesis of 4-aminotetrahydrocarbazole de
rivatives from iro-[1H-carbazole-1,2'-(1,3)-dithiolan]-4-(9H)-one 1 is
described. The structure of compound 6 has been confirmed by X-ray st
ructure analysis.
